Direbeak Hatchling in slot two. 121 once Gnomefeaster kills Ikky bring in Direbeak Hatchling and use Falcosaur Swarm! Then use Preadatory Strike. The fight is won at that point no need fr the owl pet who did not pull it off for me.
I somehow don't have any owls leveled up, so I used a Bloodgazer Hatchling (2/*/1) for the second pet. After Ikky's death, I used Predatory Strike and then Savage Talon, and Gnomefeaster was dead. Didn't need the third pet!
